Positioning your projector Choosing a location Your room layout or personal preference will dictate which installation location you select. Take into consideration the size and position of your screen, the location of a suitable power outlet, as well as the location and distance between the projector and the rest of your equipment. Your projector is designed to be installed in one of four possible installation locations: 1.
Obtaining a preferred projected image size The distance from the projector lens to the screen, the zoom setting (if available), and the video format each factors in the projected image size. The projector should always be placed horizontally level (like flat on a table), and positioned directly perpendicular (90° right-angle square) to the horizontal center of the screen. This prevents image distortion caused by angled projections (or projecting onto angled surfaces).
How to determine the position of the projector for a given screen size 1. 2. Select your screen size. Refer to the table on page 19-20 and find the closest match to your screen size in the left columns labelled "Screen size". Using this value, look across this row to the right to find the corresponding average distance from screen value in the column labelled "Average". This is the projection distance. 3. On that same row, look across to the right column and make note of the "Vertical offset (mm)" value.
